Subject: [PATCH net-next] ipv6: rearm router solicitaion timer when setting new tokenized address

When a new tokenized address gets installed we send out just one
router solicition. We should send out `rtr_solicits' in case one router
advertisment got lost.

So, rearm the timer as we do in addrconf_dad_complete.
